## HOW TO DECRYPT — STEP BY STEP (using your 8-bit machine)
1. Type in the NERDLETTER DECRYPTOR BASIC program (see below)
2. RUN
3. When it asks, type the PAD groups from the appropriate page:
`VLGKU` then `JXCYH` then `LYMDC` then `ETLUB`
4. Then type the CIPHERTEXT groups:
`HLXIB` then `JACJP` then `ERXHN` then `EFM`
5. The machine will instantly print the plaintext!
## RESULT YOU SHOULD SEE:
```
MARYHADALITTLELAMB
```
(Add spaces by hand: “Mary had a little lamb”)
This is perfect secrecy — no computer on Earth can read it without this exact Day Book page.
